, -CLOSURE r012. BOTTLES, JARS, AND OTHER nEcErrAc Es.

To all whom it may concern:

Be it known that I, CHARLES LESLIE NEW- LAND, a subject of His Majesty the King of England, and I resident of Eltham, in the county of Kent, Kingdom of England, have invented certain new and useful Improvements in Closures ffo'r Bottles, Jars, and

Other Receptacles, pf which the following is a specification.

Thls 1nvent10n refers to improvements 1n closures for bottles, jars and other receptacles of the kind comprising a resilient disc having a central bulged portion capable of being sprung into opposite positions on each side of a horizontal plane, and-having a plurality of marginal fingers integral with said central portion and adapted to be moved away from or into contact with the beaded edge of the receptacle according to whether the flexible disc is sprung in towards the said fingers or away from same.

Heretofore in such closures it has been proposed in orderto prevent the bulgin disc from being depressed and the cap or c osure accidentally opened, to provide the said disc with a circumferential marginal portion or upstanding flange,but it hasbeen-found 1n practice that if this marginal portion or up-' standing flange is made of sufficient size to position the central bulge entirely below the level of its upper edge, it has a detrimental efi'ect upon the grip of the fingers on the receptacle and also upon the springing ofthe central disc.

Now according to the present invention in order to overcome the said disadvantage I provide the body of the disc or cap witha plurality of upstanding projections near its periphery which may be stamped up from the metal thereof or otherwise provided thereon. The said projections may be of. any convenient shape or configuration and they are so arranged or disposed as not to interfere with the free movementof the fin-. gers when the central disc is sprung.

.In' order that the present invention, may be clearly understood and readily carried. into eflect it is hereinafter described withreference to theaccomp'anying drawings, in

Figure 1 is an outside elevation of a cap constructed in accordance with this invention and applied to a bottle or jar;

Figure 2 is a plan view of said cap;

Figure 3 is a transverse vertical section of the said capshowing the same in its closed Specification of Letters Patent. Patented Aug. 15, 1922. Application filed May 2, 1922. Serial No. 557,888.

Figure 7 is a side elevation of the. cap

shown in Figure 6, and

Figure 8 is a sectional elevation of a portion of the cap showing one of the projections'pulled up on its under or concave side. 7 In carrying the present invention into Jeffeet I may, as shown in Figures 1 to. 4, provide such a disc a with a single semispheri- V showing the cal upstanding projection b in-the central disc near the middle of each depending finger, c and preferably spaced equi-distant from each of the slots cl dividing the fingers c from each other. I

In a further slightly modified construction, instead of providing each finger with a single projection I may, as shown in F igure 5, provide two projections b b for each finger c and space them in relation'thereto" so that they come adjacent to the said slits d, thus leaving a central portion ofthe disc inthe middle of the finger plain or free.

In a further slightly modified construction, instead of providing semispherical or like projections b the'se'projections may be flattened, as shown in Figures 6, and 8, so as to. coincide with the periphery of the disc a to give a more-or less sinuous appearance to the edge thereof, as shown in Figure 7, providing in effect a discontinuous flange, the raised or crest portions of the.

said projections 6 coming in'the centre of each finger c and merging away into the flat edge portion of the dlsc just'before or adjacent to the slits ddividing the fingers,

In certain-cases it maybe desirable or necessary; as shown in'Figure 8,.in order to provide a flat or levelmarginal surface on the underside of the flexible disc a, to' fill in with metal or other suitable materia1 e the recessesformed therein by the projections- I) being stamped up from they metal thereof. A further advantage arising from the use of my inventiori, is that the projections b will U not only serve to prevent "accidental opening when packed but should any receptacle already be open the pressure 0? packing will cause the closure to be sealed. This function is due to the fact that the projections are always above the level of the disc a even when it is bulged outwardly, as shown in Figure 3, and also by reason of the fact that the centre of the projection is always outside the high point or fulcrum line of the beaded edge 7 of the receptacle, an arrangement which ensures that pressure on the projections 6 will cause the disco to be swung outwards into the position shown in Figure 3. This is of reat advantage as the closures canbe loosiy placed in position on the receptacles and can be closed thereon in a suitable press by hand or other power.

It will thus be seen that by thepresent arrangement I am enabled to provide projections of sufiicient height to leave the central bulge on the flexible disc completely below their level and at the same time not to destroy the rigidity of the depending fingers and theeentral disc, or to reduce the grip efiect of the fingers on the edge of the receptacle.

What I claim is v j 1. A closure for bottles, jars and other receptables, comprising a resilient disc having a central bulged portion capable of becap.

i aae aoe sprung into opposite positions on each s1 e of a horizontal plane, a plurality of marginal fingers integral with. the central bulged portion and; adapted to, be moved away from or into contact with the beaded edge of the receptacle according to whether the flexible disc is sprung in towards said fingers or away from same, and a plurality of upstandin projections near the periphcry of the said disc, the saidprojections providing in effect a discontinuous flange and being so arranged or disposed that they always tend to protect the bulged portion of the disc and also assist in the closing of the 2. A closure according to claim 1, in which one or more projections are provided near the periphery of the central disc bet-ween each of the divisions of the fingers.

3. A closure according to claim 1, in which the projections are of circular formation, substantially as described.

In testimony whereof I have hereunto signed in name;
